Filed: 1991-08-01
Abstract: 2088479 9203021 PCTABS00010 A decoder screen (80) is intended for use in an imaging system in which the screen is disposed between a viewer and a composite image containing alternate portions of two images which together form a stereoscopic pair. The decoder screen (80) includes a surface on which is printed a pattern of alternating clear and opaque areas, for example, parallel stripes or a chequerboard pattern, and a plurality of lenticular elements (82). The lenticular elements may be semicircular lenses or elongate prisms. In either case, the lenticular elements are so shaped that the apparent pattern of clear and opaque areas perceived by one of the viewer's eyes is the inverse of the apparent pattern perceived by the viewer's other eye when looking at the decoder screen and a composite image positioned immediately behind it. Thus, each of the viewer's eyes perceives parts of only one of the two images forming the stereoscopic pair, resulting in an overall 3-D effect.

Title: Powered rail coin sorter
Inventor: ADAMS THOMAS P
IPC: G07D9/00
Filed: 1992-06-05
Abstract: A sorter for coins has an inclined disc (55) which carry coins on flights (56) from a hopper (11) to an inclined track (13) comprises a rail (21) with a lip on the rear of the rail (21). The surface of the track is defined by a series of adjustable gates (20a-20h) which define openings (24a-24h) with the rail (21) that are sized to the diameters of the coins to be sorted. Coins entering the track (13) are engaged by a series of belts (14, 15) having projections (66). When the coins distort the projections (66) upon entering the track (13), they are forced against the rail (21) and are thereafter carried by the belt (14) along the track until they reach their respective opening. At the opening, the release of the distorted projections (66) imparts a force which lifts the coins over the lip and through the opening.
